Qur'an 66:3

وَإِذْ أَسَرَّ ٱلنَّبِىُّ إِلَىٰ بَعْضِ أَزْوَٰجِهِۦ حَدِيثًا فَلَمَّا نَبَّأَتْ بِهِۦ وَأَظْهَرَهُ ٱللَّهُ عَلَيْهِ عَرَّفَ بَعْضَهُۥ وَأَعْرَضَ عَنۢ بَعْضٍ ۖ فَلَمَّا نَبَّأَهَا بِهِۦ قَالَتْ مَنْ أَنۢبَأَكَ هَـٰذَا ۖ قَالَ نَبَّأَنِىَ ٱلْعَلِيمُ ٱلْخَبِيرُ

When the Prophet confided a fact unto one of his wives and when she afterward divulged it and Allah apprised him thereof, he made known (to her) part thereof and passed over part. And when he told it her she said: Who hath told thee? He said: The Knower, the Aware hath told me.
